CountdownTimer 문제

Question

충돌이 발생하여 이유를 찾을 수 없습니다. final SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences (this); final int timer = prefs.getInt ("TIME", 86400000);

new CountDownTimer(timer, 1000) { 

     public void onTick(long elapsed) { 

      if(elapsed/3600>=10&&(elapsed/60000)/24>=10)   
        time.setText(elapsed/3600000+":"+(elapsed/60000)/24); 
        else 
         if(elapsed/60000>=10&&(elapsed/60000)/24<10) 
         time.setText(elapsed/36000+":"+"0"+elapsed/60000);    
         else if(elapsed/60000<10&&(elapsed/60000)/24>10) 
          time.setText("0"+elapsed/36000+":"+elapsed/60000);  
          if(elapsed/60000<10&&(elapsed/60000)/24<10) 
          time.setText("0"+elapsed/36000+":"+"0"+elapsed/60000); 

         SharedPreferences.Editor editor = prefs.edit(); 
           editor.putLong("TIME",elapsed); 
           editor.commit(); 
     } 
     public void onFinish() { 

     } 
     }.start();

Answer 1

당신은 java.lang.Integer에 읽는됩니다

final int timer = prefs.getInt("TIME", 86400000); 

을하지만, 당신이 java.lang.Long의 저장됩니다

SharedPreferences.Editor editor = prefs.edit(); 
editor.putLong("TIME",elapsed); 
editor.commit(); 

그래서 그들 중 하나를 변경하는 것이 좋습니다 그들은 일치한다.
